Preliminary Response of Some Rice Varieties to Soil Ph and Texture in Parts Kano State, Nigeria is a well-researched topic, it is to be used as a guide or framework for your Academic Research.
Drought is one of the adverse effects of climate change. It is a repetitive meteorological event and a very complex phenomenon occurring naturally which influences environmental factors, vegetation,
agriculture, humans and wildlife plus the local economies. Most rice farmers in the developing countries are faced with the challenge of climate change which affects rice production. Rice yield is affected by soil physicochemical properties like soil textural class and pH and other meteorological factors. This study’s objective was to determine the effect of standardized precipitation index (SPI), meteorological data and
soil physicochemical properties on 1000 grain weight, days to maturity and grain yield in kg/ha of some rice varieties. A field experiment was conducted in Bayero University Kano experimental plots, Kano
State Nigeria simultaneously on six rice varieties (Dan China, Faro 44, Jamila, Nerica 1, Nerica 2 and YarDass) in the form of RCBD (Randomise complete block design). The soil textures of the two units used in this study differ in the two locations. Unit one was classified as loamy sand with the pH value of 5.4while unit two was sandy loam with the pH value 5.6. A significant increase (p<0.05) in grain weight (1000 grain) and grain yield (kg/ha) was observe in loamy sand soil which recorded 27.2g and
5030kg/ha respectively compared to sandy loam soil with the values 23.8g and 3830kg/ha. The rice varieties also matured early on loamy sand which was contrary to what was observed on a sandy loam
soil. The rice variety Dan China had the best grain quality on both loamy sand and sandy loam soil. Jamila had the best yield in kg/ha on loamy sand soil while Nerica 1 had the best on sandy loam soil. In
terms of the ability to mature early it was Nerica 2 that recorded the lowest number of days compared to the other varieties in both loamy sand and sandy loam. Nerica 1 was the most consistent rice variety
in this study when all the varieties were compared.
Rice is becoming important staple foodin both Africa and Latin America. Despite the recent increase in rice production since the start of the Green Revolution, rice remains one of the most protected food commodities in world trade (Muthayya et al., 2014). One of the most important natural resources limiting agricultural production is water (Dou et al., 2016). The production of food has been affected in several countries by drought (Singh, 2002; Okpara and Tarhule, 2015). As a result, water has to be efficiently utilized in order to avoid the aggravation of drought due to climate change. Usually the efficiency in water management is mostly evaluated by water productivity (WP), which is defined as the ratio of
the marketable crop yield over actual evapotranspiration (Zwart and Bastiaanssen, 2004; Dou et al., 2016). Soil can also play significant roles in the production of rice in terms of water holding capacity. Soil textures have a strong potential of affecting soil available water capacity
(AWC). Usually, soil with more clay content contains more organic matter than those with less due to the fact that a greater physical protection are attributed to clay(Dou et al., 2016; Six et al.,2000) The fertility of a soil and the level of acidity or alkalinity play an important role in determining the yield of the crops, which can be affected by intensive farming, hence the reason why proper soil quality management is required to sustain high yield in rice production (Talpur et al., 2013).
